To all whom it may .con-cern.'

Be it known that I, LEsLIn P. GRnnNfa citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have'in'vented certain new and useful Improvements in Scrapersof Whichthe following is a specification.

My invention relates `to improvements in. Scrapers, especially adapted for moving material, such as earth, sand, gravel, and the .forming a partof this specification, and in which,V

Fig. 1 is a side View, .shownp'artially lin section, of a scraper embodying the invention, and Y Fig. 2 is a top plan viewof the same.

The preferred form of construction as illustrated in the drawings,l Vvcomprises a scraper member 3 which is preferably sub-- 'stantially rectangular in form'with a closed bottom 4 and a closed rear end 5, the front and top being open. rPhe front edge of the bottom 4 is r'e-enforced by a combined wear and bumper plate 6 as indicated, and branch cables 7 are secured tothe front ends of the sides of said scraper member and to a forward drag cable '8 as shown. The sides of the scraper member 3 are provided at the rear with yrearwardly extending arms 9 pivotally connected to the lower cross bar 10 of the substantially triangular rocker frames 11 pivoted at 12 on a sled-like member 13. Branch cables 14 are connected with the upper crossbar 15.0f the rocker frames 11, being led thereto under guideV pulleys 16 as shown. The ends of the branch cables 4 are connected with the usual rear drag cable employed in such scraper mechanisms. A bumper 17 is arranged on the sled 13 to contact with the plate 6 when the scraper member is lifted onto the sled as indicated in the dotted lines in Fig. l. Branch cables 18 also connect the upper bar 15 of the rocker frames 11 with the forward drag cable 8 as shown. Y

In use the scraper is operated by dragment ,ofv the rocker, framel stantially as described.

2. VA scraper comprising'a sled-like mem-y material tov bemovedby means of the forward drag-cable V8 in the usual `way. Scraperxmember 3 collects'aload of the materialand Yconveys the same tothe desiredl i* ging-the same lforwardly over Athe' area Y point in the' Lusual way.V By .makingfthev i scraperA member-inV the *formY indicatedhwith aI-closedbottom,v the same is. ycapable .of

carrying a comparatively large l,load with small; expenditure of'gpower. VIlVhen. the point at which it; isV desiredv to .deposit the carried material f is reached, the forward dra g cable operated to draw the parts rearward.

Vcable is slacked away .and the rear dragh The'i first effect of ,rearward tension o'n-fV 1 branch .cables willy be to swing thev rear end of the Y scraper member, Vupwardly to dump the same and then carry said scraper member onto vthesled as indicated by thedottedflinesinV I"ig.1,the bumper plate -6 contactingwith the 'bumper 17 to jar looseJ any material stilleclinging within the scraper member.` -Af suitable stop kblock 19 is provided -on the sled 13 to contact with the crossbar 15 andlimit the'forward move By this means large quantities of'material-may-be readily transferred from one point to the other, and readily discharged when desired by Vmerely reversing the tension on the cables.

While' I have illustrated and described the preferred formV of construction for,

nov

Having described my inventi0nwhat I claim as new and desire to secure by Izet- Y ters Patent is `:Y y 1. A scraper comprising asled-hke' mem# ber; a scraper member'separate from and performing its scraping operations substantially independently of said sled ;v cables connected to drag said members forward and back; and means operable by said cables whereby said scraper member-will be lifted onto said sled when said cablesare operated to drag said membersback and extended into operative position when 'said cables are f operated to drag said'members forward, sub

ber; a scraper member separate from and performing its scraping operations substair tially independently of said sled; cables connected to drag said members forward and back; and means operable by said cables,`

whereby said scraper member will be dumped and lifted onto. said sled when vsaid cables are Voperated to ldrag said. members back and extended into operative position when said cables are operated to drag saidv members forward, substantially asdescribed.A A

3. A scraper comprising a sled-Alike mem- A ber; a scraper member separate from and performing its scrapingoperations siibstanf tia-ily independently of said sled; cables connected to drag said members forward and back; a rocker member jniou-nted on said sled operatively connected with said scraper member; and operative .connections kbetween said cables and said rocker member, whereby said sciaper'memberwill be lifted onto said sled when said cables areloperated to dragsaid members back and Vextended-into operative positionwhen said cables are operated lifted onto fsaid sled vwhen said cables are operated to drag said members back and eXA tended into operative position when `said cables are operated to drag said members for gwai'd, substantially `as described.

5. A scraper comprising a scraper member; a sled-like member; a vrocker member mounted on said sled member; cables conn nected with said roclrenniember and arranged-to drag the scraper forward and v back; a pivotal connection between said rocker member and said scraper member whereby said scraper member will be lifted onto said sled member by'rearward rocking of said rocker member;A and a connectionbc tween the forward end of said Scraper me'm-y 1 ber and the forwardly operating:r cable, sub` staiitially as described.

G. Ir scraper comprisingl a substantially rectangular scraper men'i'ber having a closed l bottom and rear end ybut open at Yits for ward end and top; a forward drag cable;

connected with the forward end `of said scraper; a sied; a rocker pivoted on said sled and pivotally connected V-wtli the rear end of said scraper member; a rear dragfcable operably connected with said rockerg and an operative connection with said .rocker` and said forward drag cable, substantially as described. y

In testimony whereof I have signed my name to this specification in the presencerof two subscribing witnesses` LESLIE P. GREEN.-
